Abstract

The embodiment of the present invention discloses a battery state detection device, which is suitable for being respectively connected with a battery pack and a DC / DC conversion circuit, and includes a voltage comparator, a feedback control circuit and a state detection unit, and the DC / DC conversion circuit includes an input terminal , feedback terminal and output terminal, the input terminal is connected to the battery pack, the feedback terminal is connected to the feedback control circuit, the output terminal is connected to the feedback control circuit, the state detection unit and the electrical equipment, and the voltage comparator is connected between the battery pack and the feedback control circuit Among them, the DC / DC conversion circuit is suitable for receiving the battery voltage through the input terminal, receiving the feedback voltage through the feedback terminal, and outputting the output voltage through the output terminal; the voltage comparator is suitable for comparing the battery voltage and the reference voltage, and outputting the switching signal; the feedback control circuit It is adapted to receive the output voltage and the switch signal, and control the output feedback voltage based on the switch signal to control the output voltage; and the state detection unit is adapted to determine the battery state of the battery pack according to the output voltage.

Description

technical field [0001] The invention relates to the technical field of state detection, in particular to a battery state detection device. Background technique [0002] In industrial sites, many important key electrical equipment are powered by batteries. For some electrical equipment that is powered by batteries and has explosion-proof requirements, the batteries must be isolated in a sealed explosion-proof box, and the box cannot be opened at will to prevent explosion accidents caused by electric sparks generated by the battery. [0003] That is to say, the battery explosion-proof box and the electrical equipment are independent of each other, and the battery cannot be directly connected to the subsequent circuit. Although this ensures safety, it also makes it impossible to directly obtain the battery status. Once the battery power is too low or the battery is damaged, the electrical equipment cannot work normally, which may cause unpredictable losses. Therefore, it is ...
